Rotation around circular path

[tvtomas]

Hello
I’m trying to create the effect seen in the GIF below:

I already tried altering the “Rotate around point” node but it looked too complex for the minimal knowledge that I have.

Closest I got was using “Rotate around point” in combination with velocity set as a sine wave in the Z-axis and cosine in the X and Y-axis, but the orientation is only correct in a certain part which I don’t know how to fix:

Any help is welcome!

Approach is pretty simple. Take a point, and rotate it around the big circle. At the same time, rotate another point around resulting point in a plane, which is is perpendicular to circle tangent. Use the second point as center of a particle to render.
